Park Jack Angle Alignment
Figure 2-1
Park Jack Angle Alignment
The jack mount angle should be adjusted to position the
park jack vertical while supporting the cutter hitch. This
angle will vary depending on the number and size of
stroke control spacers placed on the lift cylinder rod.
1.
With cutter hitched to a tractor, lower cutter to storage
height.
2. Shut tractor down properly before dismounting. Refer
to
3. Install park jack (#7). See
page 14. Check jack angle. If jack is not vertical,
proceed with step 4 below.
4. Remove hex nut (#3), lock washer (#5) and carriage
bolt (#2).
5. Loosen 1" hex nut (#4). Do not remove.
6. Rotate jack mount (#1) to align jack as near vertical
as possible.
7.
Replace 1/2"-13 x 1 1/2" GR5 carriage bolt (#2) and
secure with lock washer (#5) and hex nut (#3).
Tighten hex nut to the correct torque.
8. Tighten 1" hex nut (#4) to 645 ft-lbs.
9. If moving cutter, skip to step 10. If unhooking cutter,
on page 26 for detailed
instructions.
10. If cutter is to be moved, remove park jack (#7) from
hitch frame and attach it to the left-hand wing storage
base. Make sure base of park jack is level with or
lower than the head, especially after the wings are
folded up. See cover picture for correct positioning.

NOTE:
If cutter is not hitched securely to a tractor,
support blocks should be placed under the front
skid shoes to support cutter while aligning the park
jack vertically.
NOTE:
Refer to decal (#6) and instructions below
for jack alignment and torque value instructions.
Level Cutter Decks
These adjustments should be made with your cutter
hooked to the tractor operating the unit or to a tractor
having the same drawbar height.
Level Center Deck
Refer to Figure 2-2 & Figure 2-3 on page 29:
1.
With cutter attached to a tractor, disengage power
take-off, and park on a level, hard surface. Place
tractor gear selector in park or set park brake.
2. Using hydraulic lift, adjust center deck height so that
front skids (#2) are 2 to 3 inches above ground.
3. Wait for blades to come to a complete stop and then
fold wings up to transport position.
4. Shut tractor engine off and remove switch key before
dismounting from tractor.
5. Set transport locks to keep deck from falling. See
on page 34 for instructions.
Front Skid Position (Chain Guards Removed for Clarity)
Figure 2-2
6. On both sides of the center deck are continuous
hinges (#1). Measure distance from bottom of hinges
to ground at the front and back. They should be equal
distance off the ground at the back and 1" closer to
the ground at the front than they are at the back.
If continuous hinges are too high at the front:
a. Loosen jam nuts (#3).
b. Loosen adjusting nuts (#4) an equal amount to
lengthen both leveling rods until hinges (#1) are
inclined from front to back by 1" with the front
being closer to the ground than the back.
If continuous hinges are too low at the front:
a. Loosen jam nuts (#3) several turns.
b. Tighten adjusting nuts (#4) an equal amount to
shorten both leveling rods until hinges (#1) are
inclined from front to back by 1" with the front
being closer to the ground than the back.

NOTE:
Unscrewing coupler nuts (#4) will lengthen
leveling rods and lower front of cutter. Tightening
coupler nuts (#4) will shorten leveling rods and raise
front of cutter.
